Uploading images

Hi,

I have Worpress 2.0.2 installed and it works fine, except for the imges upload. I have GD activated on the server (bundled (2.0.28 compatible)) but when I try to upload an image that is bigger than the thumbnail settings I het the correct write or edit page, no error, but the upload/browse screen remains blank. I have searched this forum and the internet but I cannot find any similar problems. Does anybody know what could cause this behavior? I’m getting desperate…
